CAUTION
Keep the unit in its static-proof
bag until installation.
Otherwise, you run the risk of
damage to the printed circuit
board from electrostatic
discharge.
Accessories
Low cost temporary
temperature sensor, 10K
thermistor with RJ11 (1”
long), that enables space
control if the permanent room
or duct sensor is not installed
(pack of 25).

Expected Installation Time
New controller installation
10 Minutes
Replacement (old controller has
removable terminal blocks)
6 Minutes
Replacement (old controller does
not have removable terminal
blocks)
16 Minutes
NOTE:
You may require additional time for
database work at the field panel.
Required Tools and Equipment
Small flat-blade screwdriver (1/8-inch blade
width)
Cabling and connectors
Cordless drill/driver set
ESD wrist strap
Prerequisites
Wiring conforms to NEC and local codes and
regulations. For further information see the
Wiring Guidelines Manual
(125-3002).
Room temperature sensor installed (optional).
24 Vac Class II power available.
Supply power to the unit is OFF.
Any application specific hardware or devices
installed.
Air velocity sensors installed in ducts.
NOTE:
If the controller is being installed on a
box with 1 or more stages of electric
heat, the 550-809 MOV with pre-
terminated spade connectors must be
installed across the manufacturer-
supplied airflow switch. MOVs can be
installed at the time the controller is
factory mounted; coordinate with the
box manufacturer prior to order
placement. For field installation, see
Metal Oxide Varistor Kit Installation
Instructions
(540-986).
NOTE:
A low-cost temporary RTS (540-
658P25) is available that plugs into the
RTS port on the controller, providing
temperature input and actual space
control until a permanent RTS is
installed.
Installation Instructions
NOTE:
All wiring must conform to national and
local codes and regulations (NEC, CE,
etc.).
1. Secure the mounting rail in the controller’s
desired location.
2. Place the ESD wrist strap on your wrist and
attach it to a good earth ground.
3. Remove the controller from the static proof bag
and snap it into place on the mounting rail.

4. Connect the FLN.
5. Connect the point wiring (see
Wiring Diagram
s).
6. Plug the room temperature sensor cable into the
RTS port.
7. Connect the power trunk. DO NOT apply power
to the controller without first consulting the
specialist. This TEC is designed to work with 2-
wire AC power (Neutral and Phase (hot) at 24
Vac +/-20%. Use of the earth terminal is optional
and if used it should be connected to the nearest
earth ground (building steel, conduit or duct work
(if earthed)).)
CAUTION
It is very important that the
neutral that supplies the TEC
be earth grounded at the source
of the 24 Vac power.
Possible erratic equipment
operation or damage if neutral
is left floating.
The installation is complete.
Wiring Diagrams
CAUTION
The controller’s DOs control 24
Vac loads only. The maximum
rating is 12 VA for each DO. An
external interposing relay is
required for any of the following:
• VA requirements higher than
the maximum
• 110 or 220 Vac requirements
• DC power requirements
• Separate transformers used to
power the load
(for example part number 540-
147, Terminal Equipment
Controller Relay Module)

Wiring for AI with a 4 to 20 mA Sensor.
NOTE:
If the voltage/current switch is set to
current and a 4 to 20 mA sensor is
connected to an AI, then special
wiring requirements must be followed.
NOTE:
When wiring any actuator that uses a 0 to
10V control signal and ties AC neutral to DC
common, an additional wire must connect
the actuator AC neutral to the DC common
of the PTEC/TEC AO being used to control
the actuator.
